I saw "collido..." and thought "collliding things", like that desktop toy with hanging balls that clack-clack back-and-forth. Here's the best picture I can find (not a very good picture, but the cover of a very good album):

Unlike many crude screensavers which are inaccurately described as "kaleidoscopic," my screensavers are true kaleidoscope simulators: They use a two mirror "mandala" reflection system, much like the best fine-art kaleidoscopes, and they are entrancing and mesmerizing!

On the other hand, I've noticed a lot of X screensavers are based on Physics modeling. simulations of Colliding Galaxies, Lorenz attractors, Descartes Circle theorem demos, all kinds of stuff.http://www.jwz.org/x...ensaver/screenshots/
